No, but it should be from your browser: all SetInternet2 does is to
switch to use Internet Explorer internals. cURL (and hence RCurl)
knows nothing about IE's settings.
Note that if all you need is the proxy details, then you don't need
SetInternet2: see ?download.file. However, many sites need to
authenticate to the proxy ....
